推荐答案

要找到一个程序的安装路径（在Windows上）的理想方法是从注册表中读取它。大多数安装程序将创建一个包含安装路径该程序的注册表项。正是这个关键，并根据问题的程序是什么将被命名为变化而变化。

The ideal way to find a program's installation path (on Windows) is to read it from the registry. Most installers will create a registry key for that program that contains the installation path. Exactly where this key is and what it will be named varies depending on the program in question.

要找到，如果该程序在注册表中的一个关键，开放式注册表编辑器'并使用编辑>查找选项尝试并找到该程序名称的关键。如果这样的键存在，可以使用在该的RegistryKey 类阅读.NET框架库。

To find if the program has a key in the registry, open 'regedit' and use the Edit > Find option to try and locate a key with the program name. If such a key exists, you can read it using the RegistryKey class in the .NET Framework library.

如果程序没有一个注册表项，那么另外一种办法就是要求用户找到与打开文件对话框中的.exe文件，虽然这显然是不理想的。

If the program does not have a registry key then another option is just to ask the user to locate the .exe file with the OpenFileDialog, although this is obviously not ideal.
